Na-P1 zeolite was synthesized from coal fly ash with a 2-3 M NaOH solution at 100-150℃. Other than these conditions, four kinds of zeolites were also found along with Na-P1. Faujasite, hydroxy sodalite, analcime, and cancrinite phases were identified under various conditions. Na-P1 zeolite exhibited high CEC of 215 meq/100 g and strong affinity for Pb and Sr metal ions. These results give the application for the removal of heavy metal ions from the conversion of waste fly ash to Na-P1 zeolite.
